NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements of Sumner Municipal Light Plant (utility) have been prepared in conformity withaccounting principles generally accepted in the United States of America as applied to enterprise funds ofgovernmental units. The Governmental Accounting Standards Board (GASB) is the accepted standard-setting body for establishing governmental accounting and financial reporting principles.

The significant accounting principles and policies utilized by the utility are described below.

REPORTING ENTITY

The utility is an enterprise fund of the City of Sumner, State of Iowa, located in Bremer and FayetteCounties. It has a separate governing body, the Board of Trustees, who are appointed for staggered six-year terms by the Mayor and approved by the City Council. The Light Plant maintains its own system ofbooks, records, and accounts apart from the City. The City is audited separately. The Light Plant provideselectrical service to the citizens in and around Sumner.

For financial reporting purposes, the utility has included all funds, organizations, agencies, boards,commissions and authorities. The utility has also considered all potential component units for which it isfinancially accountable and other organizations for which the nature and significance of their relationshipwith the utility are such that exclusion would cause the utility’s financial statements to be misleading orincomplete. The Governmental Accounting Standards Board has set forth criteria to be considered indetermining financial accountability. These criteria include appointing a voting majority of an organization’sgoverning body and (1) the ability of the utility to impose its will on that organization or (2) the potential forthe organization to provide specific benefits to or impose specific financial burdens on the utility. The utilityhas no component units which meet the Governmental Accounting Standards Board criteria.

MEASUREMENT FOCUS, BASIS OF ACCOUNTING AND FINANCIAL STATEMENT PRESENTATION

The utility is presented as an enterprise fund of the municipality. Enterprise funds are used to account foroperations that are financed and operated in a manner similar to private business or where the governingbody has decided that the determination of revenues earned, costs incurred, and net income is necessaryfor management accountability.

The financial statements are reported using the economic resources measurement focus and the accrualbasis of accounting. Under the accrual basis of accounting, revenues are recognized when earned andexpenses are recorded when the liability is incurred or economic asset used. Revenues, expenses, gains,losses, assets, and liabilities resulting from exchange and exchange-like transactions are recognizedwhen the exchange takes place.

GASB issued Statement No. 68 - Accounting and Financial Reporting for Pensions - an amendment ofGASB Statement No. 27 and Statement No. 71 - Pension Transition for Contributions Made Subsequentto the Measurement Date - an amendment of GASB Statement No. 68, in June 2012 and November2013, respectively. These statements establish accounting and financial reporting standards for theaccounting and reporting to the utility's cost-sharing multiple employer pension plan. This statementreplaces the requirements of Statement No. 27, Accounting for Pensions by State and LocalGovernmental Employer. The utility adopted these statements effective January 1, 2015.

NOTE 6 - NET POSITION

GASB No. 34 requires the classification of net position into three components - net investment in capitalassets, restricted, and unrestricted. These classifications are defined as follows:

Net investment in capital assets - This component of net position consists of capital assets, includingrestricted capital assets, net of accumulated depreciation and reduced by the outstanding balances of anybonds, mortgages, notes, or other borrowings that are attributable to the acquisition, construction, orimprovement of those assets. If there are significant unspent related debt proceeds at year-end, theportion of the debt attributable to the unspent proceeds are not included in the calculation of netinvestment in capital assets. Rather, that portion of the debt is included in the same net positioncomponent as the unspent proceeds.

Restricted - This component of net position consists of constraints placed on net position use throughexternal constraints imposed by creditors (such as through debt covenants), grantors, contributors, orlaws or regulations of other governments or constraints imposed by law through constitutional provisionsor enabling legislation.

Page 19



NOTE 6 - NET POSITION (cont.)

Unrestricted net position - This component of net position consists of net positions that do not meet thedefinition of "restricted" or "net investment in capital assets."

When both restricted and unrestricted resources are available for use, it is the utility's policy to userestricted resources first, then unrestricted resources as they are needed.

The following calculation supports the electric net investment in capital assets:

NOTE 7 - EMPLOYEES RETIREMENT SYSTEM

The utility implemented GASB No. 68, Accounting and Financial Reporting for Pensions – an amendmentof GASB Statement No. 27, and GASB No. 71, Pension Transition for Contributions Made Subsequent tothe Measurement Date – an amendment of GASB Statement No. 68, effective January 1, 2015.

General Information about the Pension Plan

Plan Description. IPERS membership is mandatory for employees of the utility, except for thosecovered by another retirement system. Employees of the utility are provided with pensions through acost-sharing multiple employer defined benefit pension plan administered by Iowa Public Employees’Retirement System (IPERS). IPERS issues a stand-alone financial report which is available to the publicby mail at 7401 Register Drive P.O. Box 9117, Des Moines, Iowa 50306-9117 or at www.ipers.org.

IPERS benefits are established under Iowa Code chapter 97B and the administrative rules thereunder.Chapter 97B and the administrative rules are the official plan documents. The following brief descriptionis provided for general informational purposes only. Refer to the plan documents for more information

Page 20



NOTE 7 - EMPLOYEES RETIREMENT SYSTEM (cont.)

Pension Benefits – A regular member may retire at normal retirement age and receive monthly benefitswithout an early-retirement reduction. Normal retirement age is age 65, anytime after reaching age 62with 20 or more years of covered employment, or when the member’s years of service plus themember’s age at the last birthday equals or exceeds 88, whichever comes first. (These qualificationsmust be met on the member’s first month of entitlement to benefits.) Members cannot begin receivingretirement benefits before age 55. The formula used to calculate a Regular member’s monthly IPERSbenefit includes:

A multiplier (based on years of service).

The member’s highest five-year average salary. (For members with service before June

30, 2012, the highest three-year average salary as of that date will be used if it is greater

than the highest five-year average salary.)

If a member retires before normal retirement age, the member’s monthly retirement benefit will bepermanently reduced by an early-retirement reduction. The early-retirement reduction is calculateddifferently for service earned before and after July 1, 2012. For service earned before July 1, 2012, thereduction is 0.25 percent for each month that the member receives benefits before the member’s earliestnormal retirement age. For service earned starting July 1, 2012, the reduction is 0.50 percent for eachmonth that the member receives benefits before age 65.

Generally, once a member selects a benefit option, a monthly benefit is calculated and remains the samefor the rest of the member’s lifetime. However, to combat the effects of inflation, retirees who beganreceiving benefits prior to July 1990 receive a guaranteed dividend with their regular November benefitpayments.

Disability and Death Benefits - A vested member who is awarded federal Social Security disability orRailroad Retirement disability benefits is eligible to claim IPERS benefits regardless of age. Disabilitybenefits are not reduced for early retirement. If a member dies before retirement, the member’sbeneficiary will receive a lifetime annuity or a lump-sum payment equal to the present actuarial value ofthe member’s accrued benefit or calculated with a set formula, whichever is greater. When a memberdies after retirement, death benefits depend on the benefit option the member selected at retirement.

Contributions - Effective July 1, 2012, as a result of a 2010 law change, the contribution rates areestablished by IPERS following the annual actuarial valuation, which applies IPERS’ Contribution RateFunding Policy and Actuarial Amortization Method. Statute limits the amount rates can increase ordecrease each year to 1 percentage point. IPERS Contribution Rate Funding Policy requires that theactuarial contribution rate be determined using the “entry age normal” actuarial cost method and theactuarial assumptions and methods approved by the IPERS Investment Board. The actuarialcontribution rate covers normal cost plus the unfunded actuarial liability payment based on a 30-yearamortization period. The payment to amortize the unfunded actuarial liability is determined as a levelpercentage of payroll, based on the Actuarial Amortization Method adopted by the Investment Board.

In 2015, pursuant to the required rate, Regular members contributed 5.95 percent of pay and the utilitycontributed 8.93 percent for a total rate of 14.88 percent.

The utility’s total contributions to IPERS for the year ended December 31, 2015 were $26,709.

Net Pension Liabilities, Pension Expense, and Deferred Outflows of Resources and DeferredInflows of Resources Related to Pensions - At December 31, 2015, the utility reported a liability of

Page 21




$209,604 for its proportionate share of the net pension liability. The net pension liability was measuredas of June 30, 2015, and the total pension liability used to calculate the net pension liability wasdetermined by an actuarial valuation as of that date. The City’s proportion of the net pension liability wasbased on the City’s share of contributions to the pension plan relative to the contributions of all IPERSparticipating employers. At June 30, 2015, the utility’s collective proportion was .004216 percent whichwas a decrease of .000190 percent from its proportion measured as of June 30, 2014.

For the year ended December 31, 2015, the utility recognized pension expense of $15,786.

At December 31, 2015, the utility reported deferred outflows of resources and deferred inflows ofresources related to pensions from the following sources:

Actuarial assumptions. The total pension liability in the June 30, 2015, actuarial valuation wasdetermined using the following actuarial assumptions, applied to all periods included in the measurement:

Actuarial valuation date June 30, 2015Measurement date of net pension liability (asset) June 30, 2015Actuarial cost method Entry ageAsset valuation method Fair market valueLong-term expected rate of return 7.5%, compounded annually,

net of investment expense,including inflation

Discount rate 7.5%Salary increases

Salary increases 4.0 to 17.0%, average, includinginflation.

Mortality RP-2000 Mortality Table

The actuarial assumptions used in the June 30, 1015 valuation were based on the results of actuarialexperience studies with dates corresponding to those listed above.

Mortality rates were based on the RP-2000 Mortality Table for Males or Females, as appropriate, withadjustments for mortality improvements based on Scale AA.

Long-term expected Return on Plan Assets. The long-term expected rate of return on pension planinvestments was determined using a building-block method in which best-estimate ranges of expectedfuture real rates of return (expected returns, net of pension plan investment expense and inflation) aredeveloped for each major asset class. These ranges are combined to produce the long-term expectedrate of return by weighting the expected future real rates of return by the target asset allocationpercentage and by adding expected inflation. The target allocation and best estimates of arithmetic realrates of return for each major asset class are summarized in the following table:

Asset ClassLong-term RealRate of Return

Page 23




Discount Rate - The discount rate used to measure the total pension liability was 7.5 percent. Theprojection of cash flows used to determine the discount rate assumed that employee contributions will bemade at the contractually required rate and that contributions from the City will be made at contractuallyrequired rates, actuarially determined. Based on those assumptions, the pension plan’s fiduciary netposition was projected to be available to make all projected future benefit payments of current active andinactive employees. Therefore, the long-term expected rate of return on pension plan investments wasapplied to all periods of projected benefit payments to determine the total pension liability.

Sensitivity of the utility' proportionate share of the net pension liability (asset) to changes in the discountrate. The following presents the utility’s proportionate share of the net pension liability (asset) calculatedusing the discount rate of 7.50 percent, as well as what the utility’s proportionate share of the net pensionliability (asset) would be if it were calculated using a discount rate that is 1-percentage-point lower (6.50percent) or 1-percentage-point higher (8.50 percent) than the current rate:

NOTE 8 - COMMITMENTS AND CONTINGENCIES

WALTER SCOTT JR. NO. 4

During 2002, the utility along with fourteen other private and municipal utilities entered into agreements tojointly construct a coal generating plant in Council Bluffs, Iowa. Construction was completed in 2007 andplaced into operation in 2008. The agreement states the utility has a 0.14% undivided interest in theconstruction and operation of an electric generation station known as Walter Scott, Jr. Unit No. 4 (WS4),or about 1.0 MW’s of generation capacity. See Note 4 for total cost and related accumulated depreciationfor WS4. Operation costs and depreciation associated with WS4 are reflected in the statement ofrevenues, expenses and changes in net position.

N.I.M.E.C.A

The utility is a member of the North Iowa Municipal Electric Cooperative Association (NIMECA), acooperative consisting of 13 municipalities located in Iowa. NIMECA was formed to consolidate theelectric resources of its members and to serve as a joint power supply. NIMECA is also a member of CornBelt Power Cooperative (Corn Belt). The utility contracts with N.I.M.E.C.A. to provide for its power needs.During the year ended December 31, 2015, $461,039 was paid for power pursuant to this agreement.

NOTE 8 - COMMITMENTS AND CONTINGENCIES (cont.)

N.I.M.E.C.A (cont.)

On January 1, 1989, NIMECA, acting as agent for its members, entered into a Common TransmissionSystem (CTS) agreement to combine the transmission capacity of Corn Belt and the members ofNIMECA. The agreement provides for an 18.6% undivided ownership interest in the transmission linecapacity of Corn Belt or which the utility has a 6.21% interest. See Note 4 for the total cost and relatedaccumulated depreciation to date the utility has invested in the CTS. The agreement also requires theutility to fund its share of capital improvements through monthly assessments if needed. As ofDecember 31, 2015, the balance in the CTS capital improvement accounts is $158,719 and monthlyassessments of $3,000 were paid during 2015.

The Board of Directors of Corn Belt and NIMECA has allocated earnings to their members in the form ofpatronage dividends. The dividends are payable in the future at the discretion of both Boards. The balanceof deferred patronage dividends receivable at December 31, 2015 was $24,060.

Claims and Judgments

From time to time, the utility is party to various pending claims and legal proceedings.

NOTES TO REQUIRED SUPPLEMENTARY INFORMATION - PENSIONFor the Year Ended December 31, 2015

Changes of benefit terms:

Legislation passed in 2010 modified benefit terms for current Regular members. The definition offinal average salary changed from the highest three to the highest five years of covered wages.The vesting requirement changed from four years of service to seven years. The early retirementreduction increased from 3 percent per year measured from the member’s first unreducedretirement age to a 6 percent reduction for each year of retirement before age 65.

In 2008, legislative action transferred four groups – emergency medical service providers, countyjailers, county attorney investigators, and National Guard installation security officers – fromRegular membership to the protection occupation group for future service only.

Benefit provisions for sheriffs and deputies were changed in the 2004 legislative session. Theeligibility for unreduced retirement benefits was lowered from age 55 by one year each July 1(beginning in 2004) until it reached age 50 on July 1, 2008. The years of service requirementremained at 22 or more. Their contribution rates were also changed to be shared 50-50 by theemployee and employer, instead of the previous 40-60 split.

Changes of assumption:

The 2014 valuation implemented the following refinements as a result of a quadrennialexperience study:

Decreased the inflation assumption from 3.25 percent to 3.00 percent

Decreased the assumed rate of interest on member accounts from 4.00 percent to

3.75 percent per year.

Adjusted male mortality rates for retirees in the Regular membership group.

Reduced retirement rates for sheriffs and deputies between the ages of 55 and 64.

Moved from an open 30 year amortization period to a closed 30 year amortization

period for the UAL beginning June 30, 2014. Each year thereafter, changes in the

UAL from plan experience will be amortized on a separate closed 20 year period.

The 2010 valuation implemented the following refinements as a result of a quadrennialexperience study:

Adjusted retiree mortality assumptions.

Modified retirement rates to reflect fewer retirements.

Lowered disability rates at most ages.

Lowered employment termination rates

Generally increased the probability of terminating members receiving a deferred

retirement benefit.

Modified salary increase assumptions based on various service duration.

The 2007 valuation adjusted the application of the entry age normal cost method to better matchprojected contributions to the projected salary stream in the future years. It also included in thecalculation of the UAL amortization payments the one-year lag between the valuation date and theeffective date of the annual actuarial contribution rate.

Internal Control Over Financial Reporting In planning and performing our audit of the financial statements, we considered Sumner Municipal Light Plant’s internal control over financial reporting (internal control) to determine the audit procedures that are appropriate in the circumstances for the purpose of expressing our opinions on the financial statements, but not for the purpose of expressing an opinion on the effectiveness of Sumner Municipal Light Plant’s internal control. Accordingly, we do not express an opinion on the effectiveness of Sumner Municipal Light Plant’s internal control. Our consideration of internal control was for the limited purpose described in the preceding paragraph and was not designed to identify all deficiencies in internal control that might be material weaknesses or significant deficiencies and therefore, material weaknesses or significant deficiencies may exist that were not identified. However, as described in the accompanying schedule of findings and responses, we identified deficiencies in internal controls that we consider to be material weaknesses. A deficiency in internal control exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent, or detect and correct, misstatements on a timely basis. A material weakness is a deficiency, or a combination of deficiencies, in internal control such that there is a reasonable possibility that a material misstatement of the entity’s financial statements will not be prevented, or detected and corrected on a timely basis. We consider the deficiencies described in the accompanying schedule of findings and responses to be material weaknesses. These material weaknesses are items II-A-15, II-B-15, and II-C-15.

Compliance and Other Matters As part of obtaining reasonable assurance about whether the Sumner Municipal Light Plant’s financial statements are free from material misstatement, we performed tests of its compliance with certain provisions of laws, regulations, contracts, and grant agreements, noncompliance with which could have a direct and material effect on the determination of financial statement amounts. However, providing an opinion on compliance with those provisions was not an objective of our audit, and accordingly, we do not express such an opinion. The results of our tests disclosed no instances of noncompliance or other matters that are required to be reported under Government Auditing Standards. Comments involving statutory and other legal matters about the Sumner Municipal Light Plant’s operations for the year ended December 31, 2015, are based exclusively on knowledge obtained from procedures performed during our audit of the financial statements of the Sumner Municipal Light Plant. Since our audit was based on tests and samples, not all transactions that might have had an impact on the comments were necessarily audited. The comments involving statutory and other legal matters are not intended to constitute legal interpretations of those statutes. Sumner Municipal Light and Plant’s Response to Findings Sumner Municipal Light Plant’s response to the findings identified in our audit is described in the accompanying schedule of findings and responses. Sumner Municipal Light Plant’s response was not subjected to the auditing procedures applied in the audit of the financial statements and, accordingly, we express no opinion on it. Purpose of this Report The purpose of this report is solely to describe the scope of our testing of internal control and compliance and the results of that testing, and not to provide an opinion on the effectiveness of the entity’s internal control or on compliance. This report is an integral part of an audit performed in accordance with Government Auditing Standards in considering the entity’s internal control and compliance. Accordingly, this communication is not suitable for any other purpose.

SCHEDULE OF FINDINGS AND RESPONSES For the Year Ended December 31, 2015

FINDINGS The audit identified the following material weaknesses:

II-A-15 Criteria: Statement on Auditing Standards AU-C Section 265, Communicating Internal Control Related Matters Identified in an Audit requires auditors to report a deficiency if SMLP is not able to prepare its financial statements or has material adjusting journal entries.

Condition: The 2015 financial statements were prepared during the course of the audit by Baker Tilly Virchow Krause, LLP. Cause: As a result of the size of the entity, SMLP has elected for the auditors to prepare the financial statements so operations can continue as normal on a day to day basis. Effect: SMLP’s financial records may be materially misstated before the annual audit is completed. Recommendation: The utility should consider becoming more involved in the preparation of the annual financial statements in future years.

Management’s Response: Management will consider this recommendation in future years.

II-B-15 Criteria: According to Statement on Auditing Standards AU-C Section 315, Understanding the

Entity and Its Environment and Assessing the Risks of Material Misstatement, sufficient internal accounting controls should be in place that mitigate the risk of material misstatement in the financial records due to fraud or error.

Condition: During the audit, we identified that proper segregation of duties was not in place. Cause: During 2015 SMLP did not have the resources required to adequately segregate all accounting functions at all times. Effect: Due to the lack of segregation, there is a risk that material misstatements due to fraud or error may go undetected in SMLP’s financial records. Recommendation: The utility should increase the amount of management’s involvement in the day-to-day operation of the system. Management’s Response: As staffing levels permit, management will become more involved in day-to-day activities, realizing that responsibilities in a limited number of individuals is not desirable from a control point of view.

II-C-15 Criteria: According to Statement on Auditing Standards AU-C Section 315, Understanding the Entity and Its Environment and Assessing the Risks of Material Misstatement, collectively known as the risk assessment standards, sufficient internal accounting controls should be in place that mitigate the risk of material misstatement in the financial records due to fraud or error.

Condition: During the audit, we identified the following areas of internal control could be improved:



Page 39

CONTROLS OVER RESTRICTED CASH ACCOUNTS

1. Separate restricted cash accounts have not been established for each of the debt issues which is a requirement of the bond resolution.

CONTROLS OVER ACCOUNTS PAYABLE/DISBURSEMENTS

1. The accounts payable general ledger account and list of invoices included in accounts payable are not formally reconciled. Considering the cash basis of accounting is followed this account should be regularly reviewed to ensure the general ledger account is cleared to zero after each disbursement is made.

CONTROLS OVER UTILITY BILLING AND RECEIPTING

1. There is not a segregation between the receipting and receivables function. 2. There is not a review of new customers entered into the system or a regular review of billing rates.

CONTROLS OVER PAYROLL

1. Persons preparing the payroll are not independent of other personnel duties and restricted from access to the payroll account.

CONTROLS OVER FINANCIAL REPORTING

1. Journal entries are not prepared by someone independent of processing transactions in the account. 2. Account reconciliations are not performed by someone independent of the processing of transactions

in the account. LOGICAL AND PHYSICAL ACCESS SECURITY SMLP is highly reliant on critical systems and the security that governs them. While logical restrictions are in place, best practices indicate that other steps are necessary to ensure the integrity of data. We recommend the following:

Enforce a unique and private password and log-in for each employee Enforce length and character restrictions for passwords. Length and character restrictions provide an

additional level of security to help protect data and systems. Best practices suggest passwords should be changed every 45 days, require a minimum of 6 characters, require strong passwords (combination of alphanumeric, numeric and special characters), and passwords should be remembered so users cannot reuse recent passwords.

Develop a process to ensure the server room is locked at all times.

Cause: During 2015 SMLP did not have the resources required to implement controls at the ideal levels to prevent these weaknesses. Effect: Due to the lack of controls, there is a risk that material misstatements due to fraud or error may go undetected in SMLP’s financial records. Recommendation: We recommend that these areas be reviewed and strengthened.

Management’s Response: Management will consider enhancing these controls in future years, realizing that responsibilities in a limited number of individuals are not desirable from a control point of view.
